Research on Color Watermarking Algorithm Based on Video Frames

LIN Ke-zheng,SHI Jing,TANG Yuan-xin(School of Computer Science and Technology,Harbin University of Science and Technology,Harbin 150080,China)  
In order to improve the content authentication of watermarking,an algorithm on color watermark embedding in video frames is presented,choosing every channel of I-frame to do DCT respectively,and extracting singular values after each blocked,then,choosing the color watermark corresponding channel to do DWT,and extracting singular values after scrambling on low frequency,after that putting watermark singular values into carrier ones according to the algorithm and acquire watermark video image by reconstructing three color channels.Attack experiments have been done,and the results show that the algorithm has a better extracting ability and certain robustness.
